Removable retention appliances were applied to 20 treated orthodontic patients, and their occlusal contact points were determined from occlusal registrations taken at the beginning and the end of retention. Furthermore, to determine the results at the end of retention, the occlusion of 20 treated patients was compared with a control group of another 20 subjects who had an ideal occlusion. During the retention phase the number of contacts in centric occlusion increased significantly. No significant difference was observed with regard to the location of contacts. Whereas the number of ideally located contacts was similar to that in the control group, differences were observed in actual and canine contacts between the groups. At the end of retention, the balancing side contacts in lateral movements and the posterior contacts in protrusive movements were generally determined as near contacts and showed a similarity to the control group. In order to maintain the occlusal stability that is needed for the success of orthodontic treatments, ideal occlusal contacts and localization of contacts in centric and eccentric occlusion should be considered.
对20名接受正畸治疗的患者使用了可摘式保持器，并根据保持开始和结束时获取的咬合记录确定其咬合接触点。此外，为了确定保持结束时的结果，将20名接受治疗患者的咬合情况与另一组20名具有理想咬合的对照受试者进行了比较。在保持阶段，正中咬合时的接触点数量显著增加。在接触点的位置方面未观察到显著差异。虽然理想位置的接触点数量与对照组相似，但两组之间在实际接触点和尖牙接触点方面存在差异。在保持结束时，侧向运动中的平衡侧接触点和前伸运动中的后牙接触点通常被确定为接近接触点，并且与对照组相似。为了维持正畸治疗成功所需的咬合稳定性，应考虑理想的咬合接触点以及正中与非正中咬合时接触点的定位。
